Inference and optimal design of multiple constant-stress testing for generalized half-normal distribution under type-II progressive censoring

The generalized half-normal (GHN) distribution and progressive type-II censoring are considered in this article for studying some statistical inferences of constant-stress accelerated life testing. The EM algorithm is considered to calculate the maximum likelihood estimates. Fisher information matrix is formed depending on the missing information law and it is utilized for structuring the asymptomatic confidence intervals. Further, interval estimation is discussed through bootstrap intervals. The Tierney and Kadane method, importance sampling procedure and Metropolis-Hastings algorithm are utilized to compute Bayesian estimates. Furthermore, predictive estimates for censored data and the related prediction intervals are obtained. We consider three optimality criteria to find out the optimal stress level. A real data set is used to illustrate the importance of GHN distribution as an alternative lifetime model for well-known distributions. Finally, a simulation study is provided with discussion.     

Humor and satire in politics: Introducing cultural sociology to the field

The landscape of political humor and satire is changing rapidly, and it is becoming an increasingly relevant aspect of our culture. Although scholars have been actively trying to capture this change, majority of the existing frameworks for understanding humor and satire in politics still reduce these phenomena to mere genres or rhetoric tools. In addition, they provide insufficient accounts concerning the reception of humor and satire, and neglect to interpret and explain what they communicate. In the article, a general understanding of humor and satire outside of a political context, followed by an overview of studies discussing humor and satire in politics through their applications in social movements, as leadership tools, and through their manifestations in mass media has been presented. Lastly, a cultural sociological perspective to the field has been introduced. It has been argued that approaching humor and satire in politics through a structural hermeneutic method of the Strong Program will enable us to recognize and treat political humor and satire as autonomous and complex cultural systems which carry an internal power to move people.     

Public school accountability,workplace culture,and teacher morale

Educational scholars claim that teacher morale has suffered from accountability pressures and constrained professionalism, but exactly what is most diminished by these pressures remains unclear. Drawing on recent theoretical work on public school organizational culture, we hypothesize that accountability pressures hurt teacher morale and increase the risk of turnover by undermining the professional culture of the school and by diminishing teacher cooperation and trust. We find support for this hypothesis in a national sample of teachers in 2011–12, and a follow-up survey from 2012–13. The analyses test whether a collective pedagogical teacher culture, comprised of professional culture and teacher collaboration, buffers the impact of these pressures that diminish teacher morale. Counter to past research, we find that a strong collective pedagogical teacher culture does not buffer teachers from the ill effects of negative workplace conditions in the form of accountability pressures. We also find that accountability pressures in the form of district dismissals are associated with a higher likelihood of teachers leaving their school, and this relationship is not mitigated by strong professional culture. We conclude that accountability pressures partly undermine goals of improving performance and equity in public schools by sowing seeds of teacher dissatisfaction and contributing to teacher turnover, thus thwarting student achievement in struggling schools.     

‘Becoming’ a possible threat: masculinity,culture and questioning among unaccompanied young men in Sweden

A debate on masculinity and immigration rose across Europe in 2015 after an incident with sexual harassments taking place in Cologne, Germany. The incident refuelled a debate positioning unaccompanied young men as a possible threat. This article is based on a research project where we during this time ethnographically followed 20 young men, having arrived in Sweden as ‘unaccompanied’ minors. The aim is to examine how the young men themselves talk about, reflect on and negotiate masculinity and gender during this period. The article concludes that masculinity cannot be approached as something stable easily being inherited or transferred from one’s origins. One difference for ‘unaccompanied’ young men is how conflicts or tensions emerging in relation to issues of gender and masculinity tend to be interpreted differently, and publicly, putting the young men in a ‘gendered situation of questioning’.     

Heteroscedastic Global Tests that the Regression Parameters for Two or More Independent Groups are Identical

Simulation results are reported on methods that allow both within group and between group heteroscedasticity when testing the hypothesis that independent groups have identical regression parameters. The methods are based on a combination of extant techniques, but their finite-sample properties have not been studied. Included are results on the impact of removing all leverage points or just bad leverage points. The method used to identify leverage points can be important and can improve control over the Type I error probability. Results are illustrated using data from the Well Elderly II study.

论传统文化与大学生核心价值观的培育

五千年生生不息的历史文化积淀是中华民族的根和魂。新时代高校如何用优秀传统文化涵养社会主义核心价值观,成为必须解决的重要课题。文章以山西警官高等专科学校2012、2013级学生为对象,进行了深入调查与研究,着重从教育改革新理念的树立、理想信念教育的加强、加大传统文化教育软硬件设施的投入和多元化教学渠道的开辟等四个方面进行了初步探索。文章认为传统文化教育与大学生社会主义核心价值观培育具有内在统一性。     

论人类命运共同体的“真、善、美”

人类命运共同体是“真”思想,它在继承马克思主义对“共同体”科学分析论述的基础上,结合当今世界发展的总体趋势不断探索、不断实践、不断发展并取得了显著成效。人类命运共同体是“和”“善”的思想,因为它充分汲取了中华文明的优秀基因,将中国传统文化中“和”与“善”的思想推向全世界。人类命运共同体是美丽的思想,因为它不仅准确把握了时代的主题,力求构建美丽新世界,还将全人类对美好生活的向往转变为现实的动力。构建人类命运共同体是马克思主义在21世纪焕发强大活力的显著象征,是中国优秀传统文化中和平思想的集中体现,是贡献给世界的中国智慧和中国方案。     

中国农村研究的主体回归与方法论创新

21世纪以来,中国农村治理研究陷入了本土化与主体性双重困境,中国农村社会基础的深度转型,农村研究方法的缺陷以及大规模村庄研究的局限,要求中国农村研究回归深度的村庄研究,尊重农民主体性。在回归村庄研究的方法论上,文章认为要突破国家政权建设理论等研究视角的局限,把市场化这一变量纳入分析视野中。村庄主位、农民主体、市场化过程同国家宏观治理体系的互动逻辑,应该构成后中国农村治理研究时代的主要内容。     

关于高校中层副职干部几个基本问题的思考

高校中层副职干部具有高校干部、中层干部和副职干部的群体特征，应当具备相应的政治、思想、道德、业务、能力和身体等方面的基本素质。高校应当按照现行干部配置规制，结合内部管理体制和工作机制任用干部。高校中层副职干部的日常活动涉及到社会、学校、家庭等多个层面，必须妥善处理好各种人事关系。
